Naomi Kisted leaves Fleur, nine, and Rocco, three, with her husband or her own mum

Speaking exclusively to Fabulous Digital, the 40-year-old said: "If a client books us economy flights and there's an opportunity for me to upgrade to business or first class, I would quite happily do that.

"We have a really good life and I want the kids to understand the value of money and the importance of working hard. They're too young to really appreciate first class.

"I’m sure some people will think ‘oh my God’ but if you’re in a position where you have these kinds of opportunities, how do you teach your kids the value of money?

"I wasn’t handed anything on a plate as a child or a teenager, I’ve worked for everything I’ve got.
